Blockchain vs Cryptocurrency

Blockchain

Blockchain is a digital, decentralized ledger that records transactions across many computers. Each transaction is stored in a “block,” and these blocks are linked together in a secure chain. Once recorded, the data cannot be easily changed, making it transparent and tamper-resistant. It is the core technology behind cryptocurrencies like Bitcoin and many other secure digital systems.

 

Cryptocurrency

Cryptocurrency is a type of digital or virtual currency that uses cryptography for security.
It operates on decentralized networks based on blockchain technology, without being controlled by a central authority like a bank or government. Transactions are verified by a network of computers and recorded on a public ledger.
Popular examples include Bitcoin, Ethereum, and Litecoin.
